Zipper - i can find a used one for sale and hemifever can still tune it for me? I dont know much about these tuners so forgive me if i ask a dumb question. I thought i remembered reading somewhere that if you buy a used one its best to make sure the previous owner unlocked it. With that being said; a few questions - does hemifever have a website and if so what is it? - what does it cost for a custom tune - and lastly is there a certain model tuner i should look for or buy a certain model number or above?


p.s. here is a pic of my new addition

I cant agree more. Sure a no name brand one will work but you get what you pay for. K&N, in my opinion, is a quality product. I installed it and went together with ease and the instructions were extremely straight forward. This stuff you buy on ebay i cant speak for but good luck!

Sean is a good tuner who has tuned our trucks for many years and understands the quirks with our pcm's. The Diablo Predator tuner to look for is the U7137, yes, make sure it is unlocked before purchase. Sometimes you can find them in the forum classifieds of the different dodge forums too. My 1st bought cai was an ebay one and it served it's purpose... I have since upgraded to one that flows more..

ebay:


current one:

Hey Fred, thanks for the reply. I was unaware that you were lucky enough to have 2 BFI intakes!? As to the programmer (to make sure i understand) - I would go and buy the diablo predator U7137, then have hemifever write me a tune per my applications on my truck, then download it and plug and enjoy my gains? Any idea what is a good price for a used one. I saw on the diablo site they are currently $264 and thats cheaper than amazon.com lol Thanks!

the way it works, buy predator.. download any updates for it. Talk to Hemifever and ask what pids to datalog. Plug diablo into truck, go to diagnostics (I think), choose the pids you need to datalog. Drive around while data logging. Then download that file and email it to Sean, he will make a tune for you and email it back. Then upload to predator and install into truck.. You can also connect it to a laptop while datalogging and then send it that way..

Thanks Fred. Now a few more questions if you dont mind - I assume with this tuner i would be able to give my vehicle really strong shifts and change (or have hemifever change) the rpm at which my vehicle shifts? In addition is this something that I have to keep plugged in all the time or just plug, download and unplug? For the record the only mods i have at the moment are exhaust and K&N CAI. I plan to do headers down the road and thats prolly where i will stop. Maybe do a level kit.

Thanks again for you info!

I just picked up a slightly used KN cold air kit, so Im glad to see this thread. I've always read/heard good things about Hemifever tuning.

Technically you can change the shiftpoints but i left it to the tuner to put the shifts in. You can make the shifts pretty sensitive or hold longer (like on mine).. no, once the tune is loaded, you can unplug the tuner.. just keep it on if you want to monitor anything. I plug mine in from time to time if i want to monitor air/fuel ratios while in closed loop or my tranny temps if I think it's warm... Since I live in Cali i had my tuner make me a 'smog' tune for emission's testing along with my custom tune, I want to take it to a dyno sometime to get a nitrous tune done. You can also change pedal/throttle sensitivity (I love that)... those are good mods you're planning, don't forget a Y pipe and a 180 tstat...

Now what exactly do you mean where your shifts 'hold longer'? I assume you mean you let the R's get up there more so before shifting ...such in tow/haul mode? I would really like to have a tuner be able to give me some nice crisp shifts...love that feeling. As to the mods - doesnt the truck already have a y pipe on it in the front? And the t-stat - I remember I have asked about this before but I cant remember why its better. Unless this truck is running upward of 250 lol. But in all seriousness a small block chevy's engine (with heat and expansion) is perfectly sealed at 220deg. I would think a hemi as well would run better above 180? Sorry I have been away from the forums for a bit lol.

Thanks again fred! I hope you dont mind me picking your brain
